OPPC cable application advantages
The new OPPC technology solves the shortcomings of current electric power ADSS and OPGW optical cables, such as electric corrosion, inability to meet cross-over distance requirements, lightning strikes, theft, line loss, etc., and more importantly, provides wiring for future deployment of distribution network automation. Cable channel. The use of power system transmission line path resources to set up OPPC fiber optic cable is a good way to meet various needs.
OPPC can overcome all the shortcomings of OPGW and ADSS, and has broad application prospects. The advantages are as follows: OPPC technology is used to optimize the transmission line design, and the energy saving effect is remarkable. In recent years, there have been repeated phenomena or reports that the OPGW has been struck by lightning. Because OPPC is compounded in the phase line, there is no serious accident of OPGW breakage and fiber breakage caused by lightning on the ground. In the reconstruction of 110 kV and 220 kV old lines, due to the problem of fiber breakage and cable breakage due to the electrical corrosion problem of ADSS, due to the grounding height of the old line, across the roads, railways, rivers and other natural environments, it is necessary The height of the tower and the distribution of the field strength are designed. Compared with ADSS, OPPC does not cause electrical corrosion or cable damage or fiber breakage due to field strength. The erection of the ADSS cable adds weight and tension to the original line, and additional line load is added, which brings potential hidden dangers to the line. Compared with ADSS, OPPC does not have the hidden danger of adding extra line load to the original line. Due to the high voltage on the OPPC and the connector box, there is an absolute anti-theft advantage.
